I am doing one POC with Camunda to adopt workflow for one of our new initiative .
I downloaded the zip file (7.11.0) from https://camunda.com/download/ . It is having the tomcat 9.0.19.
When i start tomcat with H2 DB, server comes up fine no issue. I updated the server.xml with my DB2 database details . After this , server is not coming up. I am getting these errors .
Using CATALINA_BASE: “C:\Users\abc\Camunda\server\apache-tomcat-9.0.19”
Using CATALINA_HOME: “C:\Users\abc\Camunda\server\apache-tomcat-9.0.19”
